Question

A solution of ammonia NH3(aq) is at equilibrium. How would the equilibrium

change if NH4+ were added to the solution?

Answer 1

Answer: The equilibrium will shift in the direction of
`NH_3`

Step-by-step explanation:

The chemical equation for the aqueous solution of ammonia follows:

`NH_3+H_2O\rightleftharpoons NH_4^++OH^-`

According to Le-chtelier's principle:

If there is any change in the variables of the reaction, then the equilibrium will shift in that direction of equilibrium to minimize the effect.

If we add more amount of
`NH_4^+` to the solution, more of the products will be present. But according to Le-chtelier's principle, to minimize this effect, the equilibrium will shift in the backward direction that in the direction of
`NH_3`

Hence, the equilibrium will shift in the direction of
`NH_3`
